It's like...

There are these red ones, m'kay?

With the positives 'n' the like.

They all hang out together over there, at least all the ones with the same levels 'n' them voltage thangs.

And all the blacks, what with their negatives and stuff, they all be hangin out together over thar...

eurddrue said:You put positive on your battery to voltage in on your system. Wait, you're doing the Dreamcast, aren't you. I think you need a picoPSU or something to power those, because the run off of odd voltages?

Well the picoPSU was used to decrease the size.

I am using the original Dreamcast PSU to save time.

XCVG said:You can't run the original PSU off batteries.

Really???

Dang...

That sucks.

The battery appears to be badly constipated.

yes. im going to assume, that the voltages you need are: 12v, 7.5v, and 3.7 v.AfroLH said:Well the reason I asked was because the dreamcast requires three different voltages.

And all the battery diagrams I have seen for the Dreamcast require Cellphone Batteries and AAs.

So I have another question...

Can I use Li-Po batteries to power the dreamcast?

if that is so, just get a battery like this one. then use a 7808 to get 7.4 volts, and another one, (dont know the number) to get 3.7 volts.

wire it like this:

Well the problem was that all the DC diagrams show Cell Phone Batteries so I needed to know if I needed those batteries for it to run.eurddrue said:You could use nicad for all we care.

Thanks!

Dude, you have helped me a lot with this project!

was i right about the voltages?

Yep!

Now I just need to find a regulator to Output 3.7V

well, a 7805 drops it to 5v, so it will be lower than that. maybe a 7802 or a 7803?AfroLH said:samjc3 said:'welcomeAfroLH said:samjc3 said:
